Additionally, "connected" or "coupled" as used herein may include wireless connection or wireless coupling.

Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

Figure 1 is an exemplary way to illustrate WLAN awareness.

The process of WLAN awareness may be: the initiator (initiator) initiates WLAN awareness (for example, initiates a WLAN awareness session), and there may be multiple responders (responders) to respond to it. The specific possible ways can be as shown in Figure 1 ( a), (b) and (c).

Referring to (a) in FIG. 1, when a WLAN awareness initiator (for example, a client (client)) initiates WLAN awareness, multiple associated or non-associated WLAN awareness responders (for example, three access points (AP, access point)) can respond. Here, "association" may refer to the establishment of an association connection for communication between the initiator and the responder, and "non-association" may refer to the establishment of no association connection for communication between the initiator and the responder.

As examples, clients may include, but are not limited to: cellular phones, smart phones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal Navigational Devices (PND), Global Positioning System, Multimedia Devices, Internet of Things (IoT) Devices, etc.

An AP can be a wireless switch for a wireless network, or an access device for a wireless network. The AP may include software applications and/or circuitry to enable other types of nodes in the wireless network to communicate with the outside and inside of the wireless network through the AP. As an example, the AP may be a terminal device or a network device equipped with a Wi-Fi (Wireless Fidelity, wireless fidelity) chip.

(b) in FIG. 1 is similar to (a) in FIG. 1 , but in (b) in FIG. 1 , communication can be performed between responders (APs).

Referring to (c) in FIG. 1 , both the WLAN awareness initiator and the WLAN awareness responder can be clients, and both can communicate by connecting to the same AP.

Although it is shown in (a), (b) and (c) in FIG. 1 that the client acts as the initiator and the AP acts as the responder, the disclosure is not limited thereto. can be the responder. In addition, the numbers of initiators and responders are not limited as shown in (a), (b) and (c) in FIG. 1 .

In addition, although it is only shown in FIG. 1 that the AP participates in WLAN awareness, the present disclosure is not limited thereto, for example, a PCP (PBSS (personal basic service set, personal basic service set) control point (control point)) can also participate in the WLAN perception.

For example, in the 60GHz frequency spectrum, AP/PCP can send sensing signaling, such as a directional beacon (beacon) frame, wherein the format (or content) contained in the directional beacon frame can be different from that of ordinary (or regular) signaling. The standard frame is the same, and in WLAN perception, there may be passive sensing (passive sensing), that is, the receiver only receives the sensing signaling sent by the AP/PCP, and does not send the sensing signaling. In other words, the AP/PCP can act as an initiator (also referred to as a "sender" hereinafter), and the receiver can act as a responder. Herein, the receiver may be referred to as a passive station (STA, station), which may be similar to the client described with reference to FIG. 1 .

For example, the directional beacon frame sent by the AP/PCP can be used as sensing signaling, and the receiver for passive sensing can use the sent directional beacon frame to perform WLAN sensing measurement and feed back the sensing measurement result to the AP/PCP. However, in the current research, the mechanism of passive sensing measurement is not perfect. For example, the receiver needs to know the period, direction and other information of the sensing signaling used for passive sensing, but the current research lacks corresponding supporting mechanisms. be enhanced.

In view of this, a communication method and a communication device according to the embodiments of the present disclosure are provided.

FIG. 2 is a flowchart illustrating a communication method according to an example embodiment. The communication method shown in FIG. 2 can be applied to a WLAN-aware sender device, for example, the above-mentioned AP or PCP.

Referring to FIG. 2, in step 210, a request frame is received. Specifically, the sender device receives a request frame from the receiver device. For example, the request frame may include requesting information of a beacon frame for passive sensing measurement. For example, a recipient device may be a passive station, examples of which may include, but are not limited to: cellular phones, smart phones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers ( PIM), personal navigation device (PND), GPS, multimedia devices, Internet of Things (IoT) devices, etc. In addition, although beacon frames for passive sensing measurements are described herein, the present disclosure is not limited thereto, and other sensing signaling that can be used for passive sensing measurements is also feasible.

According to an embodiment of the present disclosure, the request frame may include information about the beacon frame requested by the recipient device. In other words, through the request frame sent by the receiver device, the sender device can know the information of the beacon frame requested by the receiver device. For example, the request frame may include the sending period and sending direction of the beacon frame. In this case, the sending period and sending direction of the beacon frame included in the request frame may be pending fields, which are only used to make the sending device know the information requested by the receiving device. In addition, as a non-limiting embodiment, the sending direction information includes TRN (training sequence field) information, which is used to indicate the sending direction of the beacon frame.

According to another embodiment of the present disclosure, the request frame may further include: time stamp information for time synchronization. For example, if the passive station serving as the receiver device has not established an initial association with the AP/PCP, the request frame may further include timestamp (timestamp) information for the passive STA to perform time synchronization with the AP/PCP.

In step 220, a response frame is sent. Specifically, the sender device sends a response frame to the receiver device. For example, the response frame may include information of a beacon frame for passive sensing measurements. According to an embodiment of the present disclosure, the information of the beacon frame may include a sending period and a sending direction of the beacon frame. In this case, the sending period and sending direction of the beacon frame included in the response frame may be a specific sending period and sending direction. For example, the sending period may refer to the period in which the beacon frame will be sent, and the sending direction may refer to information such as the azimuth, elevation direction (or pattern), and/or power of the antenna when the sending device sends the beacon frame.

According to an embodiment of the present disclosure, the information of the beacon frame may further include initial sending direction information of the beacon frame. For example, the initial sending direction information of the beacon frame may refer to the starting sequence in the sending order of the beacon frame, specifically, the initial sending direction information may define the direction in which the beacon frame is sent for the first time, so that from the starting From one direction to another, beacon frames are sent sequentially in each direction according to the sending cycle for passive sensing.

According to an embodiment of the present disclosure, the response frame may further include timestamp information for time synchronization. The time stamp information can be used for time synchronization between the AP/PCP and the passive STA. Ensure accurate transmission and reception of beacon frames.

In

steps

210 and 220, the beacon frames used for passive sensing measurements may be lightweight beacon frames or regular beacon frames used only for passive sensing measurements.

In addition, in the case that the beacon frame is a lightweight beacon frame, the response frame may further include: a sending time interval of the beacon frame. By carrying the sending time interval of the lightweight beacon frame in the response frame, the receiving device can receive the lightweight beacon frame at a more accurate time for passive sensing measurement.
